Shown is a study control clownfish that has two white bars after nine days of treatment with a mock drug. In contrast, fish at the same age treated with thyroid hormone blockers had no white bars.
With its vibrant orange color and white stripes, also known as bars, the clownfish is among the most iconic sea creatures. But how does Nemo develop its distinctive look? Scientists are learning more about that process.
Orange clownfish, or Amphiprion percula, are shown in Kimbe Bay, Papua New Guinea. How quickly this fish develops its stripes depends on the sea anemone species it chooses to live in, a study has found.
Photos: Fishing, harvest of eggs blamed for drop in sea turtles
This July 5, 2017, photo shows a leatherback turtle swimming in the Pacific Ocean near Moss Landing, Calif. All seven distinct populations of leatherbacks in the world are troubled, but a new study shows an 80% population drop in just 30 years for one extraordinary sub-group that migrates 7,000 miles across the Pacific Ocean to feed on jellyfish in cold waters off California. Scientists say international fishing and the harvest of eggs from nesting beaches in the western Pacific are to blame. (Kate Cummings via AP)

Scott Benson, an ecologist and leatherback turtle expert with the National Oceanic and Atmospheric Administration Fisheries Service, looks out over the water from his research boat in Monterey, Calif., on March 25, 2021. Benson has studied western Pacific leatherback turtles for decades and recently co-authored a study that shows an 80% population drop in just 30 years for one extraordinary sub-group that migrates 7,000 miles across the Pacific Ocean to feed on jellyfish in cold waters off California.
